Single row four point contact ball slewing bearings consist of a one-piece inner and outer ring and a set of spacers, protected by integral seals. The balls are inserted into the bearings via a hole in one of the two rings and are separated by polyamide spacers. After loading the ball set and spacers, the hole is closed with a plug that conforms to the race-way contour.
Slewing rings are sealed on both sides, lubricated with a high quality grease, can be relubricated via lubrication nipples and are particularly easy to fit. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth.
Wanda slewing rings are designed as:
■ four point contact bearings
– these slewing rings without preload are robust and proven under very demanding operation; they place only slight demands on the flatness and perpendicularity of the adjacent construction.
– they are suitable for applications with low requirements for accuracy and rigidity of the bearing arrangement, for example in simple metalworking machines, wind power equipment and construction machinery.
